parts will be upgraded automatically without the need to download upgrade image
separately. During the upgrade process, images incompatible with the new-version
software will be upgraded automatically. Therefore, the upgrade information of such
images will be shown during the upgrade process.
Overview of Upgrade Function
Upgrading Image Set
Users generally expect to obtain a more reliable software version and more software
features through upgrade. In most cases, these features are related to the main
program. The device may contain multiple program images with different functions
(such as BOOT/CTRL for booting), and these program images will only work in
coordination. Therefore, the upgrade function not only provides the support to main
program upgrade, but also allows the automatic synchronized upgrade of respective
program images on the device, so that the overall device can maintain good
compatibility.
Therefore, the upgrade file contains not only the main program for rendering primary
services, but also the BOOT/CTRL images used in conjunction with the main
program. When implementing upgrade, these images will be extracted from the
upgrade file and upgrade the corresponding images on the device.
Operating Principle
The RGOS program image release for Ruijie devices is a self-extracting executable
program. The RGOS program image carries the main program image for the device.
For box devices, the RGOS program image contains main program and boot
program; for chassis devices, the RGOS program image contains the main program
and boot program for respective linecards.
During the upgrade process, the user will first need to operate in the file system to
copy the new-version RGOS program image to the device. The user can use this
new program image to install the device. During the installation process, the system
will automatically search for image to be upgraded and upgrade them one by one.
The system will automatically guarantee the compatibility of respective images after
the upgrade. No further identification by the user is needed.
As for the upgrade of stacked devices, when the main programs of member devices
are different in version, the automatic installation process will start as well. The
RGOS program image on the master device will be synchronized to salve devices
having the inconsistent version of image, and installation will commence on these
devices. After the installation, the entire stack of devices will be reset. When all
devices enter into ready state, they will be running the identical main program.
